OK so I rewrote the pipe reader to ignore end of file marker and just keep reading. The stability of squid (writing to the pipe) and my reader seems much, much better I also use nohup(1) but most of the time it seems unnecessary.

I had a go at daemonizing the reader in the process of getting it more stable but none of the statements after the fork got executed. I can't understand why my test program worked but this one didn't. The fork() seemed to work ok.

Anyway I have left that to move onto more pressing matter: Performance. The system is a proxy which tracks downloads making people pay per megabyte. When they run out of credit they can't download. As a sideline the system does censorship[1] of www content. Now the problem is that when losts of people start browsing the web the load avg goes to ~20 and everything slows to a crawl. The Mysql daemon chews lots of CPU. So I am working on caching the information and making sure that the tables are designed properly with proper indexes and keys.

Can someone please certify me :-) I am slightly more then an observer but just less then an apprentice

[1] I know, I know. You hate censorship. So do I! But I have a legal responsiblity to sheild minors using my system from that which is deemed socially acceptable as best as possible.
