They appear to be fairly random, because I am probing the same task (a unit test suite) so memory usage should be approximately the same. example: ERROR: global variable 'times' allocation failed Sometimes systemtap gives me a suggestion for which parameter should be increased (e.g. DMAXMAPENTRIES), sometimes it doesn't. I am running the probes with the following parameters: -DMAXMAPENTRIES=120000 -DSTP_NO_OVERLOAD -DMAXSTRINGLEN=4096 -DTRYLOCKDELAY=300 -DMAXSKIPPED=10000 -DMAXACTION=1000 Are these perhaps exceptionally low/high values? How should I deal with these allocation errors?
