Re: [mapserver-users] Re: Clustering and tile clipping
Unfortunately it didn't solve the problem. I tried a lot of different values though. On top of that I'm also getting a lot of [Tue Jan 17 08:50:08 2012] [warn] [client] mod_fcgid: read data timeout in 40 seconds [Tue Jan 17 08:50:08 2012] [error] [client] Premature end of script headers: mapserv.fcgi In msCleanupOnSignal. [Tue Jan 17 08:50:48 2012] [warn] [client] mod_fcgid: read data timeout in 40 seconds [Tue Jan 17 08:50:48 2012] [error] [] Premature end of script headers: mapserv.fcgi In msCleanupOnSignal. Anyone have a clue how to increase the timeout? I'm clustering 44K points. And at lower zoomlevel (values) it is taking a long time.
