RemObjects server-side service interface Service appears irregular, intermittent no response problem; RemObjects normal client initiated the request, but the server is not responding, the request timeout error occurs, the server does not generally stuck two minutes, when the server-side auto-recovery after two minutes, all client requests will continue to process the response.

develop environment
RemObjects version: RemObjects SDK for Delphi - 7.0.73.1111
Delphi Version: Delphi7
RO server-side components used: TROIndyHTTPServer with Indy 9

We found that even the simple echo time service request the time-out error will occur.

This problem is mainly due to the server about the occasional suspended animation.

3

can you create a simple testcase that reproduces this case, pls?
if you replace Indy with Synapse (client&server) or move to Indy10, this issue will be reproduced?

4

Problem is difficult to reproduce, we now find that happen 2 or 3 times a day, every fault for 2 minutes.

RO version is necessary to upgrade?
Similar environments before other customers if there is a problem?
RO latest version is compatible Indy 9?

7

not yet. You can still use your version.

if you updated to

  • synapse channels - no changes are required in RO
  • Indy 10.5.9 and later, you need to update RemObjects.inc and uncomment {.$DEFINE RemObjects_INDY10D}
  • Indy 10.2.3 - Indy 10.5.8, you need to update RemObjects.inc and uncomment {.$DEFINE RemObjects_INDY10_in_Delphi67}

after updating RemObjects.inc, you need to recompile all packages from BuildPackages_D7.bpg

Server-side applications to enable load balancing, client for each request will switch to a different server port, whether this is normal ?

yes, it is normal if doLoadBalanced is set.
