In 32-bit Synergy programs there is a hard 4 GB size limit to files that can be sorted with the SORT statement.
In version 9.1.*, the 64-bit install of Synergy used the 32-bit SORT architecture and consequently has the same limitation.
Should you encounter this problem, consider upgrading your Synergy version to 10.3.3g or higher to take advantage of improvements we made to SORT (see tracker #37060 in the 10.3.3c release notes).
