| Post subject: | Webcam - spawning too many havp threads |
Hello, I've been using havp sind 4 month now and never run into any trouble. However, today some of my users watched a webcam which caused havp to spawn 100 threads, all locked up. 15/04/2009 11:03:23 All childs busy, spawning new (now: 101) - SERVERNUMBER might be too low The URL in question was: http://la-palma-aktuell.de/cc/cam/live.html After that I had to restart havp and squid. I'm running a sandwich squid-havp-squid configuration. havp 0.89 and squid 2.6stable14. In the squid configuration there is a urlpath_regex acl on jpg so they go always direct. acl noscan urlpath_regex -i \.(flv|swf|jpg|jpeg|jpg\?|gif|png|ico|bmp|mov|avi)$ always_direct allow noscan in the havp config, the option scanimages is set to false. Can someone else reproduce the problem or does someone has a hint for me to avoid the problem? Thanks in advance, fsom |

It only seems to load 1-2 pictures per second here and always closes connection.. strange that it takes all children. Unless there are _many_ users.  Anyway, it seems your regex is wrong.. it's trying to match ".jpg?$" right now.. but there is data after ?.. maybe better one.. acl noscan urlpath_regex -i \.(flv|swf|jpg|jpeg|gif|png|ico|bmp|mov|avi)(\?|$) |

thanks for your quick reply. I altered the squid configuration like you proposed and I'm now sure that it's not a problem within havp. It is working with the InternetExplorer 6.0 but Firefox 3.0.8 is loading like 100 images/sec. This ends up with loads of open connections: 194.180.xxx.xxx:43189 80.32.214.62:80 SYN_SENT netstat -an | grep 80.32.214.62 | wc 571 3426 46251 and at some point squid cant request any other sites. Thanks again for your help, fsom |
