[Quickfix-users] ThreadedSocketInitiator hangs during shutdown

We have been encountering a fairly reproducible issue when unloading the quickfix library when there are several initiator threads. The stack info for the relevant threads is included below. When our engine tries to shut down the ThreadedSocketInitiator, the engine hangs on thread_join for thread 147418032. Thread 147418032 is hanging because it is waiting to acquire a lock; Simultaneously, thread -1210057808 is waiting to acquire the same lock. Both Threads 147418032 and -1210057808 work on (this=0x93c6340, s=2). The fact both threads are trying to remove the same connection thread makes us to think that there is some synchronization failure. We are running on the 2.4 Redhat Linux kernel. Can anyone shed some light on this issue? Thanks in advance. -Jeff Backtrace from GDB (gdb) thread apply all bt Thread 5 (Thread 147418032 (LWP 6937)): #0 0x0092c7a2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2 #1 0x00b871ce in __lll_mutex_lock_wait () from /lib/tls/libpthread.so.0 #2 0x00b83e2b in _L_mutex_lock_35 () from /lib/tls/libpthread.so.0 #3 0x08c962c4 in ??
