Rather than increasing the number of connections, I would suggest increasing the config 'heap memory per user'. The default is 4K in ASE 16sp02 - I generally recommend 16KB. If performing XQUERY functions (xmlextract, etc.), I suggest a minimum of 64KB.
But yes, you should get an N-off for the fix - but in the meantime, you might want to bump up heap memory per user to 16KB or 32KB. Increasing number of connections - while possibly has a similar affect on heap pool size - also requires extra memory for other structures (e.g. ULC, etc.) and may require more memory vs. simply increasing the heap memory per user.
