1.8 proxy won't run on FreeBSD

[frankcheong]

I have build a version 1.8 proxy using the command line below:-

exec /bin/sh "./configure" '--disable-agent' '--with-net-snmp=/usr/local/bin/net-snmp-config' '--with-curl=/usr/local/bin/curl-config' '--enable-proxy' '--with-ldap=/usr/local' '--with-mysql=/usr/local/bin/mysql_config' '--prefix=/usr/local' '--mandir=/usr/local/man' '--infodir=/usr/local/info/' '--build=i386-portbld-freebsd7.2' 'build_alias=i386-portbld-freebsd7.2' 'CC=cc' 'CFLAGS=-O2 -fno-strict-aliasing -pipe -DLDAP_DEPRECATED' $ac_configure_extra_args --no-create --no-recursion

The build is successful and I can do make install also. While when I tried to run the proxy it failed with the below error message:-

In the zabbix_proxy.conf I just configured hostname as well as path. All else left default. So what is the possible problem that I am enocuntering?

[frankcheong]

sorry, the command line used should be below instead:-

./configure --disable-agent --with-net-snmp=/usr/local/bin/net-snmp-config --with-curl=/usr/local/bin/curl-config --
enable-proxy --with-ldap=/usr/local --with-mysql=/usr/local/bin/mysql_config --prefix=/usr/local --mandir=/usr/local/man
--infodir=/usr/local/info/ --build=i386-portbld-freebsd7.2

Try to clean your semaphores.
Take a look at ipcs and ipcrm tools.

[frankcheong]

did clean the queue using the ipcrm. now ipcs -a return nothing. While the result is the same. Any other clue?

[frankcheong]

Is that related the sysctl setting of my freeBSD? What is the required sysctl setting? Pls find below the sysctl -a (cutting only related settings) for your quick reference.

[frankcheong]

eventually I have successfully get around the problem by modifying the below two setting as below:-
kern.ipc.shmall=40960000
kern.ipc.shmmax=204800000

I believe it would be too large but I really don't have an idea on how large should I modify the setting before I can get it run, so a bit overkilling. Grateful if anyone got an idea on a better setting.

[kangaroos]

Same problem with zabbix_server and same solution, thank you

[frankcheong]

Have read thru some other webpages

http://www.linuxquestions.org/questi...riable-607991/

http://www.puschitz.com/TuningLinuxForOracle.shtml#LargeMemoryOptimization

and revised the setting as belows:-

kern.ipc.shmall=409600
kern.ipc.shmmax=204800000

Though it is for linux but I guess it should be similar. While I really have no idea on the effect of tuning the shared memory? If not, I guess the default would be all available memory, so dare not setting this figures too high.

[frankcheong]

I have a linux server with default setting for shmmax and shmall as below:-

cat /proc/sys/kernel/shmmax
4294967295
cat /proc/sys/kernel/shmall
268435456

whereby it also complain can't allocation share memory with below message:-
Can't find shared memory for database cache. [No such file or directory]

Anyway, I have then switched using the PAE kernel without turning those parameter, but it works by then. Really don't know what is the problem.
