Random Network Disconnects 500 node HP ProCurve network

Last Modified: 2013-12-07
I manage a 2003 Server network with 500 nodes.  I run HP ProCurve switches and use a SonicWall Pro2040.  I have about 300 wireless users.  We have been experiencing random network drops from  servers (file, mail and Oracle DB) for the past 5 months.  I have replaced NICs, cables, switches, servers, updated OS, updated firmware,  drivers, tested cables, spoken with tier 3 HP tech support and envolved nearly a dozen network engineers, and various support folk.  I have entertained ideas ranging from EMF given off by thermostats and HVAC units to ethernet loops caused by bleeding wireless signals.  I'm baffled and need help.

Thanks in advance!

Is there any pattern in the problems? weekday? hour of day?
- pure random or related to network use?
For how long a period of time pr.incident?

Sorry- I screwed up the response.  

Is there any pattern in the problems? weekday? hour of day?  no, purely random
- pure random or related to network use?  not related to use.  1-2% of ping packets are dropped to both DB server, file server and mail server
For how long a period of time pr.incident?  Only for an instant but long enough for client to lose connectivity to above resources

Yes- the wireless hosts tend to be more flaky than the wired.
