The stacktrace is really useful. Thanks! If possible, could you install the debuginfo package and take the stacktrace?

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:
