[Trustedjava-support] Sudden errors with TPM and JTSS

[Arshad N. <ars...@st...>]

Hello,

We've been using JTSS 0.5 for two years and it has been fairly
stable.  However, suddenly without explanation, it has started
failing on almost all decryptions.  Some of the error messages
are:

-----------------------
iaik.tc.tss.api.exceptions.tcs.TcTcsException:
TSS Error:
error layer:                0x3000 (TSP)
error code (without layer): 0x04
error code (full):          0x3004
error message: unknown
additional info: Unable to determine LRU key handle

Later on, similar attempts at the operation result in:

-----------------------
iaik.tc.tss.api.exceptions.tcs.TcTpmException:

TSS Error:
error layer:                0x00 (TPM)
error code (without layer): 0x15

error message: The TPM has insufficient internal resources to perform 
the requested action.

The details of our configuration:

TPM:  STM v1.2
OS: CentOS 5.3 (64-bit)
JDK: 6 Update 16 (64-bit)
JTSS: 0.5


Any suggestions on what might be causing these problems suddenly on
something that has been behaving well for nearly two years?  Thanks.
