Problem summary
SCRIPT Data Provider may not terminate STDERR thread, resulting in a handle leak. This APAR only applies to UA running on a Windows platform using SCRIPT data provider.
Problem conclusion
Universal Agent SCRIPT Data Provider was prematurely closing the STDERR handle. This exposed a possible zombie thread condition, where STDERR thread has blocked on a READ on STDERR handle waiting for data on STDERR pipe. Subsequently, SCRIPT Data Provider thread processes script's termination, closing the STDDERR handle. This leaves STDERR thread running in blocked state, thus the STDERR thread never terminates and the result is a handle leak. The fix for this APAR is included in the following maintenance vehicle: | fix pack | 6.2.1-TIV-ITM-FP0004 | fix pakc | 6.2.2-TIV-ITM-FP0004
