Now, now, you can always do a web search on topics like "resource limits". :-) Resource Limits are a basic reasonable usage control mechanism in Unix systems. Here are my notes, which may help: Unix Resource Limits Unix systems observe resource limit settings, to prevent runaway usage which may be detrimental to the system and other users sharing it. In AIX, resource limits are globally defined in the /etc/security/limits file. By default, the root user is unlimited. At the system level, resource limits are controlled via the setrlimit() system call, per RLIMIT_* subject function values defined in /usr/include/sys/resource.h: RLIMIT_CPU CPU time in milliseconds RLIMIT_FSIZE Maximum file size RLIMIT_DATA Data size RLIMIT_STACK Stack size RLIMIT_CORE Core file size RLIMIT_RSS Resident set size RLIMIT_AS Process max total memory RLIMIT_NOFILE Max file descriptors At the user level, these areas are adjusted via the Cshell 'limit' and 'unlimit' csh commands. (Do 'limit' to see your current values.) In RedHat Linux, global settings are in /etc/security/limits.conf . "Signal 11" is included in ADSM.QuickFacts, where it is explained to be a programming error: you may feel justified to report to IBM as a TSM defect. (The Linux TSM is still the junior member of the TSM family, going through growing pains which its brethern have experienced and overcome in the past.) Searching IBM for +"segfault" +"producer thread" turns up only an old APAR, so I would advise calling in this new one. Richard Sims http://people.bu.edu/rbs
