Re: (ITS#6331) slapd freezing, not accepting further 'write' operations while 'read' operations are unaffected

Version: 2.4.17

Occasionally, I will find one of my servers (running Debian/Lenny with back-ported slapd version 2.4.17) in a state where the following occurs:

• Write operations will 'freeze' - leaving the requester at a frozen

prompt or frozen LDAP-client of some kind (from wherever the write-operation originated).

• slapd refuses to 'stop', even though it indicates that its waiting for

"0" processes to complete.

• Logs do not indicate a segfault nor any poorly terminated processes.
• Read operations on same server continue to function normally. Any data

that existed before the "freeze" is returned as it should be.

You probably hit ITS#6276, which was fixed in 2.4.18. Can you upgrade and test?
