When Apache times out during long searches (past the timeout value specifies in httpd.conf) no error is returned to the browser. If your searches seem to just die, look in /var/log/httpd/error_log for a "timeout" entry. Very large searches seem to fail, regardless of httpd.conf timeout setting. Under some browsers/conditions, subsequent seatch.cgi forms are pre-populated with the wrong year/month fields. 1999 (lowest value) seems to be a favorite. Binary output only works in tcpdump searches. Need a search progress indicator that works. When graphing, any gap in datapoints should be padded with zeros for each unused x-axis increment. Example: 00:01:00 100 00:01:01 20 00:01:02 0 00:01:03 0 00:01:04 0 00:01:05 20 00:01:06 0 00:01:07 0 00:01:08 20 00:01:09 11 Without the zeros, the range from 01:01 - 01:08 would appear to be a continuous rate. Plot using impulses or linespoints for a more accurate representation. A binary or graphical output search, with the same query specified as a previous search, should be re-run if the datasets have changed. It isn't.
