TF2 Crash Regarding "Table DynamicModels is full"

[Roy 10,832 / 0]

Hi all,

 

I just wanted to post this KB thread for any other server owners experiencing this issue. A while ago, our TF2 servers (2Fort and High Tower) were experiencing a crash after 2 - 3 days of up-time. The stack trace on Linux would look something like this:

In the console.log file which can be generated by adding -condebug to the command line, we witnessed these lines when it crashed:

 

Warning:  Table DynamicModels is full, can't add models/workshop/player/items/all_class/hwn2016_toadstool_topper/hwn2016_toadstool_topper_Medic.mdl
590/ - tf_wearable:  UTIL_SetModel:  not precached: models/workshop/player/items/all_class/hwn2016_toadstool_topper/hwn2016_toadstool_topper_Medic.mdl
L 05/02/2019 - 04:50:22: Engine error: 590/ - tf_wearable:  UTIL_SetModel:  not precached: models/workshop/player/items/all_class/hwn2016_toadstool_topper/hwn2016_toadstool_topper_Medic.mdl

 

Both servers were mostly vanilla and I found it strange that it was referring to a workshop model. We didn't have any custom models on the server. Therefore, I'd assume it was adding client's custom workshop items to the Dynamic Models table to perhaps check it.

 

I found that setting the following ConVars resolved the issue on both servers:

 

sv_allowupload 0
sv_pure -1

 

I'm unsure what CVar specifically fixed this, but I would recommend setting both of these ConVars to the values above. If I had to guess, it was sv_pure checking client's custom files and adding too many custom models to the Dynamic Models table. Though, I am not certain.

 

Just thought I'd put this out there because I couldn't find anything online regarding this crash and was honestly stumped until I saw the console.log messages.

 

I hope this helps other server owners.

 

Thank you!
