APAR status
Closed as program error.
Error description
Clearmake may erroneously report 'interference from another process' errors when a multiple build scripts, from multiple simultaneously started non-parallel builds, are spawning large numbers of short-lived child processes. This currently appears to require a system where dozens -- if not hundreds -- of users are using the system in addition to cron-scheduled builds.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: * **************************************************************** * PROBLEM DESCRIPTION: * **************************************************************** * RECOMMENDATION: * **************************************************************** When clearmake builds are running, the MVFS filesystem maintains process-specific data for each process running as part of the build environment. On busy systems, where large numbers of processes are running and therefore process ids are being recycled very quickly, it was possible that stale process data could be found and used. Clearmake would detect the stale data in the audit files and issue the "interference from another process" error.
Problem conclusion
Fixed in 7.1.1.6 and 7.1.2.3
