closes the tcp-connection which is acknowledged by the webservice
which also
resets the TCP connection.
When I disable the caching of the WSDL file for SoapClient, I get these
errors (not always, only sometimes):
Warning: SoapClient::SoapClient() [soapclient.soapclient]: failed to
create
an SSL context in /space/hom
Warning: SoapClient::SoapClient() [soapclient.soapclient]: Failed to

crypto in /space/home
This warning suggests that PHP is unable to create a SSL stream context
. By default, if you disable caching, PHP has to download the wsdl to
your /tmp directory. Is is possible you are running out of disk space in
/tmp.

Thank you for the response, but there is plenty of space to save the
WSDL file. Also, if I cache the wsdl file, the actual service calls fail
to send a request (the tcp connection is created). As the same soap
service can be accessed via http instead of https, AND http never fails,
the problem seems to be creating a SSL context for some reason. When
retrying, it works after about 10-15 seconds but fails immediately when
retrying before that.
Because https is unrealiable, I have created a http<->https tunnel using
stunnel and I have made SoapClient access using http via stunnel (that
converts to/from https stream) to the webservice. Doing this is so far
100% reliable (even without caching the wsdl file).
To me this clearly indicates that SoapClient has occasional problems
with SSL (in php 5.2.9 on Solaris).
I'll create en rc-file to ensure stunnel is started when the OS boots
and with that I have worked around the bug in SoapClient.
