Re: [geowebcache-users] Seeding + threads

[Ricardo B. <ric...@gm...>]

Hi,

I fixed this and worked fine.
But now I set it up in production enviroment and  is happening again.
Server instance is configured by the hosting company and I cant see what
could be wrong.
I have GWC_SEED_RETRY_COUNT variable set to 2 and  GWC_SEED_RETRY_WAIT  set
to 500

Server has a 4 core and 4 gigs of ram. If I set to 8 threads, 6 are droped
within the first minute. And 2 threads remain till the end.

Could this be due to other missconfigurations? Serever o tomcat issue?

pointers are very welcome.

thanks

ricardo
