There are 5 of these processes running (parent plus 4 children). Normally each uses about 90 MB RES/SIZE. However when the problem occurs they are about 2GB RES/SIZE each. The system has 4 GB memory. I thought that a malloc would not be able to grab that much memory, even with swapping as it has to be in memory. Could a malloc cause this growth in process size or need I look elsewhere? > > > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" > Look with ps ax or ps aux to understand, how much memory a program takes. Or with top it is possible to see memory usage. Greetings
