Most likely you changed the maximal event size in midas.h, but you did not re-compile all programs. The maximal event size goes into the size of the shared memory buffer, so all participating programs have to have the same setting, especially the mserver program. So do the following:
- update to the latest midas version, which is revision 4116
- modify in your midas.h only MAX_EVENT_SIZE. The other settings you modified might have bad side effects. If you increase the RPC timeout, the error will still happen, just later. It comes from the fact that you sent too big events the the server (or the logger), which refuses to take the big events or simply crashes, so the RPC call never returns and after the timeout you get the error.
- recompile all midas programs, don't forget the mserver program
- run the standard demo frontend from the distribution
I tried the above and it just worked fine for me. |
