I could see some stats from mdb-stat tool as mentioned below,

mdb_stat.exe -rne "C:\openldap\mdb\data.mdb" Environment Info Map address: 0000000000000000 Map size: 268435456 (we have set the value as *‭104,857,600,000,000‬* in mdb.c and back_mdb.h files, but it has taken only 256 MB, not sure why?) Page size: 4096 Max pages: 65536 Number of pages used: 65527 Last transaction ID: 9555 Max readers: 126 Number of readers used: 0 Reader Table Status (no active readers)

when i try to increase to set the dbMaxSize it fails,

*addDbMaxSize.ldif * has content as mentioned below,

dn: olcDatabase={1}mdb,cn=config changetype: modify add: olcDbMaxSize olcDbMaxSize: 1073741824

olcDbMaxSize: *1073741824 - stops the service in windows*

openldap \bin>ldapmodify -H ldaps://localhost:6565 -D cn=admin,cn=config -w d -f addDbMaxSize.ldif modifying entry "olcDatabase={1}mdb,cn=config"

*ldap_modify: Other (e.g., implementation specific) error (80) additional info: failed to reopen database, rc=87*

olcDbMaxSize: ‭*536870912‬ - failed as below*

openldap \bin>ldapmodify -H ldaps://localhost:6565 -D cn=admin,cn=config -w d -f addDbMaxSize.ldif modifying entry "olcDatabase={1}mdb,cn=config"

*ldap_modify: Invalid syntax (21) additional info: olcDbMaxSize: value #0 invalid per syntax*

*back-mdb.h - we added as below* #define DEFAULT_MAPSIZE (10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 1048576)

mdb.c - we added as below #define DEFAULT_MAPSIZE (10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 1048576) if ((i = mdb_env_read_header(env, &meta)) != 0) { if (i != ENOENT) return i; DPUTS("new mdbenv"); newenv = 1; env->me_psize = env->me_os_psize; if (env->me_psize > MAX_PAGESIZE) env->me_psize = MAX_PAGESIZE; memset(&meta, 0, sizeof(meta)); mdb_env_init_meta0(env, &meta); meta.mm_mapsize = DEFAULT_MAPSIZE; } else { env->me_psize = meta.mm_psize; }

*1. i am not getting why the size of the map (as per the stats info given above) - 256 MB (268435456) only ? please provide me a clue once to understand this.* *2. Kindly let me know how to get debug logs ? i use DPRINTF, DPUT in mdb.c but dint get see as logs printed.!*

*We observed this in Windows 2012 R2 and Window10 OS x64 Arch machines.*

Thanks for your reply I do know that info for windows also is it the same.? I am unable to use stats tool also.

As I already stated, the maxsize parameter specifies the maximum size the database can reach.

...

As I don=E2=80=99t see any reply from our many mails to openldap-technical@openldap.org I have created this case to clarify.

The openldap-technical list is only open to subscribers, if you want to post to it you must subscribe first.

...

Why don=E2=80=99t you forward the query to the concerned team instead closi= ng.

Your query would not be forwarded because you failed to read and/or understand the documentation. This system is for bug reports only.

...

No reply to us.!

I did reply. This is clearly shown in the ITS.

...

Please let us know answer to solve a issue.!

I already provided you the answer in my earlier response. Set an approprate maxsize setting, the default of 10MB is clearly too low.
