Since yesterday, my game has been experiencing much more frequent crashes than is normal. The game contains around 200k parts in order to depict a fairly accurate and detailed world map, which has
always made it somewhat unstable but before yesterday servers would typically last at least a few hours or up to a day before crashing. Now they’re lasting at most an hour, typically only
20-30 minutes. The game has received no updates by us since October, which presumably narrows it down to either a change Roblox has made, a vulnerability exploiters have found, or a change to an external module we use, the Adonis admin system.
A potential cause I have found is the section of server core memory labelled as ‘network/replicationCoalescing’, which seems to continually inflate up to around 3k MB, or approximately half of the server’s memory usage before the server crashes.
However, I am unsure of what causes increases to this memory usage or what ‘replicationCoalescing’ is even for, so I don’t know whether this is something an exploiter could be causing or if it’s entirely caused by something Roblox is doing.
TLDR: if anyone knows what the replicationCoalescing core memory is used for and why its memory usage could be going so high, I would really appreciate the info. Whether this is the primary cause of the increased crash frequency or not, it’s kinda worrying that something I don’t know about is suddenly
taking up so much server memory.
Apologies if this is the wrong category for this question, however I am unsure of where else it could go, and I couldn’t find anyone else who had asked about this with Google.
