[SOLVED] high cpu load java

[nean]

I have a problem with some perseverative (about every 60sec) java process which produce temporary high cpu load. (zcs-5.0.5_GA_2201.UBUNTU8.FRANKLIN on ubuntu hardy 8.04 Celeron(R) CPU 2.00GHz/1,5GB RAM)

97.5% /opt/zimbra/java/bin/java -XX:ErrorFile=/opt/zimbra/log -client -Xmx256m -Dzimbra.home=/opt/zimbra -Djava.library.path=/opt/zimbra/lib -Djava.ext.dirs=/opt/zimbra/java/jre/lib/ext:/opt/zimbra/lib/jars:/opt/zimbra/lib/ext:/opt/zimbra/lib/ext/clamscanner com.zimbra.cs.account.ProvUtil -l garpu

has someone any ideas?

first i tried to upgrade to zcs-5.0.6_GA_2314.UBUNTU8.FRANKLIN to see if its better, but it has not worked and i made a rollback.
i also had problems with my symbolic link which is not supported -> Bug 14725 - Installer fails to follow and destroyes symbolic links

i found out that /var/opt/zimbra/bin/zmprov produces high CPU Load
cat /var/opt/zimbra/bin/zmprov

exec `dirname $0`/zmjava com.zimbra.cs.account.ProvUtil "$@"

zimbra   10464  0.0  0.0   1772   492 ?        Ss   14:20   0:00      \_ /bin/sh -c /opt/zimbra/libexec/zmlogprocess > /tmp/logprocess.out 2>&1
zimbra   10465  5.3  0.3   8148  5036 ?        S    14:20   0:00          \_ /usr/bin/perl /opt/zimbra/libexec/zmlogprocess
zimbra   10552  0.0  0.0   1780   496 ?        S    14:20   0:00              \_ sh -c /opt/zimbra/bin/zmprov -l gacf | egrep '^zimbraLogRawLifetime' | sed -e 's/zimbraLogRawLifetime: //'
zimbra   10553 81.3  1.7 428760 24532 ?        Sl   14:20   0:02                  \_ /opt/zimbra/java/bin/java -XX:ErrorFile=/opt/zimbra/log -client -Xmx256m -Dzimbra.home=/opt/zimbra -Djava.library.path=/opt/zimbra/lib -Djava.ext.dirs=/opt/zimbra/java/jre/lib/ext:/opt/zimbra/lib/jars:/opt/zimbra/lib/ext:/opt/zimbra/lib/ext/clamscanner com.zimbra.cs.account.ProvUtil -l gacf

so i prevent that zmprov is used in certain periodic script, and modifies some variables with hardcoded standard values eg. in /opt/zimbra/libexec/zmlogprocess

#my $rawRetention = `${zimbra_home}/bin/zmprov -l gacf | egrep '^zimbraLogRawLifetime' | sed -e 's/zimbraLogRawLifetime: //'`;
my $rawRetention = "31d";

#my $summaryRetention = `${zimbra_home}/bin/zmprov -l gacf | egrep '^zimbraLogSummaryLifetime' | sed -e 's/zimbraLogSummaryLife
my $summaryRetention = "730d";

Thank for you're solution, it's work here.

I've tracked a similar problem down on 8.04.1 x86_64 and found that calls to /opt/zimbra/libexec/zmmtaconfig cause massive spikes in CPU usage. That file contains several references to zmprov which I presume is causing the same sort of delays as experiences by the original poster.

Does anyone have any advice on how to circumvent calls to zmprov?
