We are running a passive Xymon client 4.2.0 with msgcache enabled on AIX 5.3. msgcache exits with an IOT/Abort trap when receiving messages. The following patch to msgcache.c fixes this problem:

230c230 < char idx[20];

                                  char idx[40];

232c232 < STRBUFLEN(mwalk->msgbuf), (long)(now - mwalk->tstamp));

(int)STRBUFLEN(mwalk->msgbuf), (long)(now - mwalk->tstamp)); 529c529 < int caddrsize;

                  socklen_t caddrsize;

Best regards, Johannes
