Java - Possible that socket data transfer is blocked by too little memory? -


i'm testing software (several applications) on vserver. applications connected central server using tcp. after hours time out means no longer send keep alive packet. do, not arrive @ server. seconds after application timed out exits outofmemoryerror.

so possible socket communication between applications "blocked" because of less memory?

edit: exception before oome ioexception broken pipe.

actually relevant exception broken pipe. means have written connection had been closed peer. in other words, application protocol error.

the rest of post mere guesswork. have memory leak somewhere, , application protocol mis-implementation. find them , fix them.
