Error description
Btach program does an openpath on a hashed file and does a close without a file varaible. This worked fine in 751A but at 8.1 on solaris it is causing DataStage to appear to hang. The issue is that it is leaving the T30 semaphore locked. If we run UNLOCK T30LOCK SEMAPHORE It allows the system to continue to run. Customer also sees the same issue when importing jobs.

Problem summary
**************************************************************** USERS AFFECTED: phantom and dsapi_slave executables can take SIGBUS faults on Solaris at Information Server version 8.1. **************************************************************** PROBLEM DESCRIPTION: phantom and dsapi_slave executables can take SIGBUS faults at release 8.1.0.x on the Solaris platform. Additionally the fault occurs while the T30 semaphore is held and results in hangs of new phantom and dsapi_slave processes trying to acquire the same semaphore. **************************************************************** RECOMMENDATION: A Solaris patch has been produced which will work on both 8.1.0.0 and 8.1.0.1. ****************************************************************
Problem conclusion
On Solaris, ensure proper memory alignment in functions which acquire the T30 semaphore to avoid SIGBUS faults.
