I tried to > use a smaller value for SEMMSL but it did not help. The tunable kernel paramater "SEMMNS" defaults to 60, that's the maximal number of semaphores allowed in the system (accumulated over all calls to semget() that are active by the same time). Also, due to the crocky^H^H^H^H^H^Hfunny concept of SysV IPC, you might as well run out of semaphore IDs instead (== #calls to semget()), which is the tunable parameter SEMMNI, defaulting to 10. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
