Solaris 10 with MySQL 5.5

Question

Hi,
I have posted similar question in MySQL forums, but I'm not sure if this is due to MySQL or Solaris problem.
Does anyone know why MySQL 5.5 stops suddenly in Solaris 10 when an error ocurrs in sql script.
I run mysql from command line instead as service by next command from /opt/mysql/mysql/bin/: bash mysqld_safe --datadir=/export/home/mysql/data &.
And i have setted my-innodb-heavy-4G.cnf as /etc/my.cnf config file.
Is there any system log (other tan mysql) where can i find what is happening? how can i see who sends shutdown signal to MySQL?
Thanks

Answer 1

About permissions problem, i have tested launching MySQL as root and the problem continue.
MySQL works fine, applications (Pentaho on tomcat) works fine for a large period, and suddenly MySQL stops.
I have launched truss (truss -rall -wall) on MySQL pid and these are certain results. I cannot interpret this info. I have only detected the block when first shutdown ocurrs. Anybody is able to interpret this info? thanks.
