Server load causes crash
I have 2 proliants dl 360 g4p. Both with the exact same hardware, exact same configuration and OS. 1 server is performing great. The other one isn't. Both perform as webserver, with a total amount of 30000 visitors per minute. The first server can handle this load, the other one is hanging. On his console i see a lot of memory errors. (See attachement).
When i perform a HD read,write test on the 'good' server i estimate a 105mb/sec. When i do this on the 'bad' server i get an estimated 7.8mb/sec. Are there any more test to see what is causing this load/error/hang ?

Re: Server load causes crash
i was same problem with load.
But my problem was caused by a bug of web-application.
It launch a big number of mysql connection and ca. 450 threads, infact the load was 30.00 and the machine goin'crash.
Check with "sar" command or by "top" your load.
Regards.

Re: Server load causes crash
Well i don't think thats it. These to servers are identical twins:) same content, same OS, same software, same hardware. So, if one crashes, the other should crash to if it was a content problem.

Re: Server load causes crash
you wrote that you noticed a prominent difference in HD I/O performance while performing tests on both machines.
Are these ATA drives, and have you any hdparms tuned?
