Hi,

I am running now dotCMS 1.9.4.2 CE. I have been getting the below
warnings and errors:

I have set the cache settings to medium and allocated 4 GIGs for
dotCMS alone. I noticed that the medium settings in 1.9.4.2 are at a
wakeUpInterval = 5000, but in 1.9.2.x and 1.9.3.x were at 500.
https://svn.dotcms.org/releases/1.9.2/tags/1.9.2.1/src-conf/cache-configuration-region-med.xml
.

Since I was getting the error below I reduce the wakeUpInterval at 500
again and the site started loading really fast now, but I don't know
if this will affect the rest of the settings or I need to modify other
numbers. I also notice that the minTimeTolive is set to 0 on 1.9.2
and 1.9.3, but it is set to -1 in 1.9.4.2

I randomly allocated the 500 to the wakeUpInterval since that is how
it was set before. Is this the right setting or will this impact
other cache tasks?

Thanks,

Alex

Here are the warnings and errors:

sorry I made a mistake on my previous email, I allocated 2 GIGs alone
to dotCMS.

Thanks

For better or worse, I've actually had to make the same change for the same reason. Not sure why the settings change was made. Chris or JT might correct me on this, but the cache region files should be pluggable, so you could save those settings to your configuration plugin so that you won't have to update it in future upgrades in case they change again.

Now, my server became unresponsive out of the sudden again. The
errors that showed on the logs are below, any suggestions what I
should do to fix it?:

Check out my update on my other thread. I ran in to a similar issue. While mine didn't come from DWR, it's the same issue with being unable to get a lock on the cache. Were you also seeing the messages about the eviction queue size like me?

Yes, I was seeing these messages about the eviction queue. I did not include it back then because wanted to take one issue at a time.
