Re: MySQL malloc error on Solaris
Ubaidul, ok, there is nothing in my.cnf that can explain why memory runs out. What kind of query are you running when the memory runs out? Does 'top' show that the mysqld process size grows uncontrollably? If you are using the C client interface, do you use 'mysql_store_result()' or 'mysql_use_result()'? For huge resultsets, one of them uses a huge amount of memory in the server.
