When porting to new *ix environments, it is quite common for there to be problems getting the configuration for the semaphores to work correctly. >From the stack trace, it is hanging on a request for a mutex semaphore. rexximage should run completely single threaded, so this should never deadlock. However, the semaphore in question is already held by the current thread because of a bit of recursion at startup, so It looks like the semaphores are not properly handling nested requests.
