Re: IPC - child reporting

Define carried away? You say you access it via a browser and things aren't ok. What error is in your web server's error log? (I'm assuming you are getting an HTTP 500).

For a test, could you scale it back to just 2 and push forward? It also could be that you are forking one child for each query. Forking is expensive, so maybe you can fork a max of N processes and just eat the delay time in between for getting responses? 200 querries/20 processes would leave you 10 qpp, and at 10 seconds max for each one, 2 minues for something you do once in a while isn't bad.

Also, what is this for? Maybe you can optimize other ways.

sorry. i'm not getting a 500, it does return ok. if i pass 5, it dumps var0-4, which is fine. if i pass more than 5, it appears to call the script again for each multiple of 5: $VAR1 = '6'; $VAR2 = undef; $VAR3 = '11'; $VAR4 = undef; $VAR5 = '3'; +$VAR6 = undef; $VAR7 = '7'; $VAR8 = undef; $VAR9 = '9'; $VAR10 = unde +f; $VAR11 = '2'; $VAR12 = undef; $VAR13 = '12'; $VAR14 = undef; $VAR1 +5 = '8'; $VAR16 = undef; $VAR17 = '4'; $VAR18 = undef; $VAR19 = '1'; +$VAR20 = undef; $VAR21 = '0'; $VAR22 = undef; $VAR23 = '10'; $VAR24 = + undef; $VAR25 = '13'; $VAR26 = undef; $VAR27 = '5'; $VAR28 = undef; +Content-type: text/html $VAR1 = '6'; $VAR2 = undef; $VAR3 = '11'; $VA +R4 = undef; $VAR5 = '3'; $VAR6 = undef; $VAR7 = '7'; $VAR8 = undef; $ +VAR9 = '9'; $VAR10 = undef; $VAR11 = '2'; $VAR12 = undef; $VAR13 = '1 +2'; $VAR14 = undef; $VAR15 = '8'; $VAR16 = undef; $VAR17 = '4'; $VAR1 +8 = undef; $VAR19 = '1'; $VAR20 = undef; $VAR21 = '0'; $VAR22 = undef +; $VAR23 = '10'; $VAR24 = undef; $VAR25 = '13'; $VAR26 = undef; $VAR2 +7 = '5'; $VAR28 = undef; Content-type: text/html <etc, there's a lot more> Software error: timeout [download] i can't see a possible reason for the extra "Content-type". the actual error appears to be either the main process or the children not dying when their time is up.
