Thanks for the clarification. > Maybe you should describe your problem. The application has been working fine for almost 3 years, along with Apache, going through RELENG upgrade without problem. Now I start noticing that Apache hangs (sig 11), either manually built or port built, make buildworld hanged once with sig 11, my application hangs with sig 11. 2 options: - I added memory in the machine and the meory is causing problems. - I changed my application a little bit and it started eating other processes. Yesterday make buildworld consistenly hanged on building groff, today after cleaning the memory (using plain rubber on DIMM contacts) it is going fine (although Apache did hang since the cleaning). So I'd like to be sure that my application cannot eat other processes, so i could eliminate one cause.
