The ticket #288 about RLIM_INFINITY reminded me of a separate failure mode we noticed - the system hitting pid_max. The file `/proc/sys/kernel/pid_max` indicates the maximum number of processes on the system (in Linux, a thread is a process). By default, this is 32k - meaning there's an implicit limit of 32k threads in a single daemon. However, to be safe, we should probably limit the Xrootd threads to `pid_max - epsilon` (epsilon is maybe 2000) to account for the fact that there are likely other threads on the system! --- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/301 ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the XROOTD-DEV list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=XROOTD-DEV&A=1
