I am following this solution here http://stackoverflow.com/questions/3927690/howto-clean-a-mysql-innodb-storage-engine/4056261#comment14041132_4056261 and tried to increase my innodb_buffer_pool_size to 4G and later 1G (also 1024M) in addition to the log file size, but mysql wont start with those values. If I put it back to 512M mysql starts fine.
How can I solve this? My server is a 16GB one, and accordign to Webmin sysinfo:
Real memory 15.62 GB total, 3.13 GB used
Meanwhile I found the error log as well:
