Bugs Fixed

Reaching max session limit due to excessive Gem exits during login

If a Gem exits prematurely during the wrong point in the Gem-to-Stone login handshake, a counter in the Stone that was incremented did not get the appropriate decrement. This reduced the maximum possible sessions that could log in (from the limit set by STN_MAX_SESSIONS or license limits). (#46817)

GsFile>>position: failures for arguments over 2 billion

Calling GsFile >> position: with a argument greater or equal to 231 (2147483648) returned nil, and caused subsequent calls to GsFile >> position to return incorrect values. (#46750)

Split IdentitySet store traversal may encounter oop not allocated error

If you do a store traversal of an IdentitySet, and the report is split across traversal buffers so that the first report in a buffer starts with one of the private named instvars that is not the first instvar, the server reports the error GbsObjErrOopNotAllocated. (#46822)

Stone encountering EWOULDBLOCK risked failing to send OOB bytes

If the Stone’s send to a gem results in an EWOULDBLOCK, the Out of Band (OOB) bytes may have been lost. OOB processing supports sigAbort handling. (#46846).

Gems may crash or hang under very low memory conditions

When a machine is almost out of swap space, such that an mmap from reserved memory fails, there are cases where the Gem may crash. (#46848)

When a Gem dies due to a malloc failure, it forks a pstack to record the stack. This may hang if there is insufficient virtual memory. (#46830)
