Real Time Counter can become stuck and does not count down

[majed17]

sometimes in the browsers i use for cacti, Firefox and chrome, the real time graph counter does not count down and the graph remains black. today all the chrome real time graphs were stuck. exiting the browser many times and reopening after a while solves the issue. except a random graph of thos open stays stuck.
log says:

Finally a new bug. Whew, I thought that would never happen, or hoping maybe 😉. Anyway, I'll have a look later today.

the error mentioned might be related to creating a cpu graph, so if anything else is needed, just let me know

works

Today, 9 out of the 52 graphs opened with non decrementing timer in the real time graphs in different browsers.
