[Kolab-devel] OpenLDAP problem

[Martin Konold]

Hi,

I have seen now multiple times an OpenLDAP server hanging and using 100% cpu.

This is the trace

stat64("/kolab/var/openldap/openldap-data/__db.003", {st_mode=S_IFREG|0600, 
st_size=98304, ...}) = 0
open("/kolab/var/openldap/openldap-data/__db.003", O_RDWR|O_CREAT|O_LARGEFILE, 
0600) = 4
fcntl64(4, F_SETFD, FD_CLOEXEC)         = 0
mmap2(NULL, 98304, PROT_READ|PROT_WRITE, MAP_SHARED, 4, 0) = 0x401fb000
close(4)                                = 0

sched_yield()                           = 0

Does this look familiar to anyone?
