Communication link failure error while running a SQL agent job in SSIS

We are getting communication link failure error for a direct loading package in SSIS frequently with errors like
1)

Shared Memory Provider: Timeout error [258]. Code: 0xC004701A and failed the pre-execute phase and returned error code 0xC0202009.

2)

Shared Memory Provider: Timeout error [258]. Code: 0xC002F210. Failed with the following error: "Communication link failure". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

any suggestions regarding this issue will be greatly appreciated.

Thanks in Advance
