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?

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.
