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?
