Re: Set limit on number of threads
Hello, Under linux, each thread is not individually using the full amount of memory that shows up in ps or top. There are a significant number of shared memory pages involved, so the total memory usage isn't simply sum( RSS_thread1, RSS_thread2 ... RSS_threadN ) HTH Andrew On Mon, Aug 12, 2013 at 1:04 AM, Justinas Urbanavicius wrote: > Hi, > > I was wondering, if there is a way to limit the number of threads that > jenkins uses, at start-up i see that there are ~28 threads running > jenkins.war, and they use a lot of memory. > Don't know why there should be a need for that much threads > > Platform Linux debian x64 > Java version "1.6.0_27" > OpenJDK Runtime Environment (IcedTea6 1.12.6) (6b27-1.12.6-1~deb7u1) > OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode) > Jenkins v1.526 > > any help or info would be appreciated > > -- > You received this message because you are subscribed to the Google Groups > "Jenkins Users" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to jenkinsci-users+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/groups/opt_out. > > -- -- Andrew Melo -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.

Re: Set limit on number of threads
Check out http://yourjenkins/threadDump -- the threads mostly have nice names that explain what they're for. Maybe you have some success changing --handlerCountStartup if you're using winstone (http://winstone.sourceforge.net/#commandLine) to reduce the number of initial request handlers.

Set limit on number of threads
Hi, I was wondering, if there is a way to limit the number of threads that jenkins uses, at start-up i see that there are ~28 threads running jenkins.war, and they use a lot of memory. Don't know why there should be a need for that much threads *Platform *Linux debian x64 *Java *version "1.6.0_27" OpenJDK Runtime Environment (IcedTea6 1.12.6) (6b27-1.12.6-1~deb7u1) OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode) *Jenkins *v1.526 any help or info would be appreciated -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
