I upgraded to FC9 from FC8, I never had a problem with FC8. Now I get this error when I try to start a python app, or do anything on a regular basis. I have over 13GB free RAM, and only 2GB of it is used. The box is a dual quad core Intel Xeon 5405 with 16GB RAM. bash fork: Resource temporarily unavailable uname -a Linux XXX 2.6.25.3-18.fc9.x86_64 #1 SMP Tue May 13 04:54:47 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux free -m total used free shared buffers cached Mem: 16086 3189 12896 0 42 666 -/+ buffers/cache: 2481 13605 Swap: 1983 0 1983 In /var/log/messages this is the only weird message May 19 10:32:16 XXX kernel: possible SYN flooding on port 80.
