I have a process that is eating up 6 GB of swap space. At that point, = FreeBSD 9.3 terminates a process. However, occasionally its not the one = eating up the space. When I manually quit the process then the swap = space returns to a few KB used. The system runs fine after that. I have very little knowledge of what this process is doing internally = but would like to know what might be causing this issue. 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?
