the limits are not sql limits. they would be php time and file upload limits.
and yes, you can increase the timeout for php and the file upload size. php has LOTS of help available for it, the values are in the php.ini file for web (not the CLI version of the php.ini, that is not being used when you are on a web page, there are two copies of the php.ini file).
Also, there is a command-line lead loader that will allow virtually unlimited upload capacity. You need to scp or find some other method to upload the file, then you execute the command line lead loader and it will run for as long as it takes to load the leads.
Please don't say latest - specify your Vicidial Version and BUILD (GoAutoDial is the Installer, but you have not listed the version which is likely 2.0CE, 2.2.1 is the Vicidial Version, but you left off the BUILD). It's required to post at least Vicidial Version and Build to submit requests (after all, the board is FREE
, it's the least you can do ...)
