Hi guys,

I'm seeing a bunch of these log entries in GC log, which are logged almost ~5-6 of them every second.

: 34426K->585K(38080K), 0.0017447 secs] 83465K->49625K(122752K), 0.0018111 secs] [Times: user=0.02 sys=0.00, real=0.00 secs]

- age   3:      21240 bytes,     654792 total

- age   5:       1464 bytes,     656776 total

Is this ok, or should I modify some of my memory settings?

That's fine, you want smaller, fast GCs rather than infrequent and longer ones.
