throws java.lang.NullPointerException without stacktrace

Question

Java

Can, who faced? The bottom line is that the written server program in java, after several hours of work, starts to hellishly throw java.lang.NullPointerException errors. Moreover, without any stack trace, etc. Those. the console looks like this:

java.lang.NullPointerException
java.lang.NullPointerException
java.lang.NullPointerException
java.lang.NullPointerException
...

and is clogged with these messages quickly, in the amount of tens of thousands.

I've already checked all catch'i and put print'y everywhere - nifiga!

I have no idea where this could be coming from? exceptions without stacktrace! how can you find out?

PS: I thought for memory, but top in Linux shows 25% of the memory is occupied by Java.
