We have a number of scripts dating back to JIRA 4.2.x which use the SOAP interface. These scripts run into errors because SOAP is not returning full data. We get data chunks that are cut off at a power of 2 boundary. We have seen 8192 bytes being returned but also 16384 bytes.
Of course the result is no longer valid XML. GZIP compression is turned off for our instance.
Are there any reports on such a behavior for 5.0.x. These scripts ran absolutely stable under 4.2.x, 4.3.x, 4.4.x.
