If the search is filtering on objectclasses that don't contain this attribute, that's wasted work. Check for a matching objectclass in the filter before doing that. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10190] New: Stack space exhaustion on windows due to FD_SETSIZE

https://bugs.openldap.org/show_bug.cgi?id=10190 Issue ID: 10190 Summary: Stack space exhaustion on windows due to FD_SETSIZE Product: OpenLDAP Version: unspecified Hardware: All OS: Windows Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: libraries Assignee: bugs(a)openldap.org Reporter: varunpatil(a)ucla.edu Target Milestone: --- Setting FD_SETSIZE is only effective on Windows and BSD, and is currently set to an unreasonable default of 4096. Each fd_set is initialized with an array of file descriptors of this size; this allocates 8*4096 bytes on 64-bit machines, which quickly exhausts the small stack space on Windows. This patch sets the default to a more reasonable value of 128; the default value on Windows currently is 64. -- You are receiving this mail because: You are on the CC list for the issue.

[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.
