Hi,
I've two directory server in multimaster configuration. I've to
reinitialize all databases on 2 nd server (B) using the data of the 1st (A).
After the synchronization, server B crash with an segmentation fault.
There isn't any relevant message in the error log.
If I restart the directory server B, I've the same error.
The directory server version is 1.1.3 on Redhat5.
rpm -qi fedora-ds-base
32-bit or 64-bit?
We have fixed quite a few replication bugs since 1.1.3, including a
couple of crashes. I recommend upgrading to the latest.

I updated to the last stable version but I've the same error.
I traced the running process and I discovered that the segmentation
fault is probably caused by futex system call. I attach the tail of the
output of the strace command below.

I debugged the running process and gdb printed this stacktrace after
the segmentation fault:

I hope that these information can be useful.
The stacktrace is really useful. Thanks! If possible, could you
install the debuginfo package and take the stacktrace?
yum install 389-ds-base-debuginfo
--noriko
I attach the tails of the error log and the /var/log/messages log.
