What does the ignition performance chart means?

Noticed the below performance charts for Tag throughput and memory has a gap. What does it mean by this gap and is it normal to see this?

Thanks in advance for the advice.

The gaps might mean your client is locking up.

What do u mean my client is locking up?

There are numerous ways to lock up a client. The most common are:

  • Run out of memory (heap space) and choke while the garbage collector tries really hard to figure out what it can safely discard. All threads stop. (Your circled gaps suggest this possibility.)

  • Perform long-running operations in a foreground thread (Java Swing GUI “Event Dispatch Thread”). Halts all GUI updates. Halts any other threads that request anything from the foreground or try to deliver anything to the foreground.
