When running 184.108.40.206 frequent errors like the following are raised:
This issue was suspected to be a case of <bug:6918493> as described in eg. <note:789111.1>, however after applying <patch:6918493> the error persists although the offset may have changed slightly:
Note the "+28" changed to "+32" - this is because the code for the nstimexp() function was modified by <patch:6918493>.
The call stack will still be something like:
We see opidcl() on the stack - this function is called when we find a session where the client disappeared, ie. this is the Dead Connection Detection (DCD) that does what it is supposed to do.
Also note that we call the signal handler and then fail in nstimexp()
