My configure.log reports the following: ... configure:9519: checking for resource support configure:9540: result: enabled ...and doing the configure phase again gave in output 'checking for resource support... enabled'.
Actually, looking at validate.c in check_process(Service_T s), it seems like it never enters check_process_resources(), while it passes through check_process_state(s). The piece of code there is as follow:
if(Run.doprocess) {
if(update_process_data(s, ptree, ptreesize, pid)) {
check_process_state(s);
for(pr= s->resourcelist; pr; pr= pr->next) {
check_process_resources(s, pr);
}
} else {
log("'%s' failed to get service data\n", s->name);
}
}
As far as I understand, this happens when 's->resourcelist' is NULL, but
can you tell me when does this happen?

I have tried to replicate the problem but it woks on my computer without problems. I tried it on Debian with kernels 2.6.8.1 and 2.4.27, single CPU, 512MB RAM.In your logs i can see only one strange thing - there is no cpu usage entry for monitored process 'heartbeat'. In my case, monit reports this statistic, for example:[CEST Oct 13 23:01:46] 'slapd' zombie check passed [status_flag=0000][CEST Oct 13 23:01:46] 'slapd' cpu usage check passed [current cpu usage=0.0%] [CEST Oct 13 23:01:46] 'slapd' succeeded connecting to INET[127.0.0.1:389] [CEST Oct 13 23:01:46] 'slapd' succeeded testing protocol [LDAP3] at INET[127.0.0.1:389]I.e. it may be possible that your monit is compiled without resource monitoring support - check that your confiure phase contains following line near the end of output:resource monitoring: enabled ... and that you are not using --without-resource option.
