How do I find what's problem with error code "Access violation write/to ....***.ex4"

 

Hi,friends

I code an EA imports ws2_32.dll, call functions e.g. connect, recv, send etc.

After a period of time on some different vps, one of these vps receives an error "Access violation write to 0x00300080 in 'C:\***\MQL4\Experts\***.ex4'",

this error without code line number or anything useful. 

It is difficult to reproduce the issue.

How could I locate the issue? Is any dump files on drivers or event log  anywhere

Thanks!
