We are running SmarterMail Enterprise 100.0.9168.31407 (Feb 6, 2025) on one of our Windows servers. Yesterday and this morning the memory usage for SmarterMail spiked to between 22 and 25GB then the service crashes. We are upgrading to the newest SM version this evening to see if that will resolve it, but I just wanted to post this here in case anyone else is having the same issue. @SmarterTools team.. if you want to have a look at our server, contact me directly and I will give you access to check it out. Currently all is well, but this happened overnight for the past 2 nights. Not exactly sure what is causing it.
