Thanks to all. The problem was the static hashmap. I removed the static keyword
to the variable and problem solved.

So you have Character -> String (entity reference). Your Map is not
synchronized, but it doesn't have to be: you are only calling get() on
it so there shouldn't be any synchronization issues here.

Big buffer every time?

New Character object every time? Mmm. You might want to choose a more
optimized storage system so you don't have to create a new object every
time.

Aside from any other strange issues you are having, you might be wasting
a lot of time (and invoking a lot of GC) by creating a large
StringBuffer for every invocation. You might want some more complicated
logic to determine if you even need to create such a buffer.
Honestly, I don't see much wrong with this class. I don't see any use of
System.gc and I don't see any connection reset. Was there a post that I
missed?
