https://bugs.openldap.org/show_bug.cgi?id=10180 Issue ID: 10180 Summary: mdb.c:2185: Assertion 'rc == 0' failed in mdb_page_dirty() Product: LMDB Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: dominik(a)greysector.net Target Milestone: --- I'm experiencing a SIGABRT-induced crash in nheko, which uses lmdb for its database (~/.local/share/nheko/nheko/#hash#/{data,lock}.mdb). The assertion triggering the SIGABRT seems to be happening here: https://git.openldap.org/openldap/openldap/-/blob/master/libraries/liblmdb/… The crash happens on every nheko startup since yesterday, so I assume something added to the database is triggering it. Full backtrace from gdb: ... (gdb) run Starting program: /usr/bin/nheko [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib64/libthread_db.so.1".

[Issue 9378] New: Crash in mdb_put() / mdb_page_dirty()

https://bugs.openldap.org/show_bug.cgi?id=9378 Issue ID: 9378 Summary: Crash in mdb_put() / mdb_page_dirty() Product: LMDB Version: 0.9.26 Hardware: All OS: Linux Status: UNCONFIRMED Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: nate(a)kde.org Target Milestone: --- The KDE Baloo file indexer uses lmdb as its database (source code available at https://invent.kde.org/frameworks/baloo). Our most common crash, with over 100 duplicate bug reports, is in lmdb. Here's the bug report tracking it: https://bugs.kde.org/show_bug.cgi?id=389848. The version of lmdb does not seem to matter much. We have bug reports from Arch users with lmdb 0.9.26 as well as bug reports from people using many earlier versions.

[Issue 9736] New: pwrite bug in OSX breaking LMDB promise about the maximum value size
by openldap-its＠openldap.org 15 Apr '26

https://bugs.openldap.org/show_bug.cgi?id=9736 Issue ID: 9736 Summary: pwrite bug in OSX breaking LMDB promise about the maximum value size Product: LMDB Version: unspecified Hardware: All OS: Mac OS Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: renault.cle(a)gmail.com Target Milestone: --- Hi, I was working with LMDB and found an issue when trying to write a value of approximately 3.3GiB in the database, I dive into the LMDB source code of the mdb_put method using the lldb debugger and found out that it was not related to an issue in LMDB itself but rather a bug in the pwrite function of the Mac OS libc implementation. The pwrite function is given four parameters, the file descriptor, the buffer, the count of bytes to write from the buffer and, the offset of where to write it in the file. On Mac OS the count of bytes is a size_t that must be a 64bits unsigned integer but when you call pwrite with a number bigger or equal to 2^31 it returns an error 22 (invalid argument). LMDB was returning a 22 error from the mdb_put call and not an EINVAL because the error was cause by an internal issue and not something catchable by LMDB. I am not sure about what we can do, can we implement this single pwrite [1] as multiple pwrite with counts smaller than 2^31 in a loop, just for Mac OS? Like for Windows where we do specific things for this operating system too? I also found this issue on the RocksDB repository [2] about a similar problem they have with pwrite and write on Mac OS it seems. I understand that this is not a real promise that LMDB is specifying but rather an "in theory" rule [3]. Thank you for your time, kero [1]: https://github.com/LMDB/lmdb/blob/01b1b7dc204abdf3849536979205dc9e3a0e3ece/… [2]: https://github.com/facebook/rocksdb/issues/5169 [3]: http://www.lmdb.tech/doc/group__mdb.html#structMDB__val -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9513] New: Enhanced debug output
by openldap-its＠openldap.org 12 Feb '26

https://bugs.openldap.org/show_bug.cgi?id=9513 Issue ID: 9513 Summary: Enhanced debug output Product: OpenLDAP Version: 2.5 Hardware: All OS: All Status: UNCONFIRMED Severity: enhancement Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: hyc(a)openldap.org Target Milestone: --- While debugging ITS#9479 I needed more information on which threads were doing what actions. Also, when looking for delays/hangs/race conditions, the 1-second granularity of the debug msg timestamp was inadequate. And also, some of the debug output for the Search operation was being done in separate Debug calls for a single line of output. This gets jumbled up pretty badly if other threads are printing output as well. New patch set will extend the debug timestamp to have fractional seconds too; it will use clock_gettime for nanosecond resolution if available, otherwise use gettimeofday for microsecond resolution. Also tweak the Search debug output to only use one Debug invocation per line of output. This is MR!279. -- You are receiving this mail because: You are on the CC list for the issue.
