Oracle's chief financial officer (CFO) has resigned after spending less than five months with the company.
Greg Maffei's position had been uncertain after he missed a number of public appearances in the past two weeks.
Oracle has referred to the problems as "scheduling conflicts" and "family issues", Goldman Sachs noted in a PDF research paper.
"We have grown increasingly convinced that there are legitimate questions regarding Mr Maffei's status at the company," analysts with the investment bank wrote prior to Oracle's announcement.
Oracle co-president Charles Philips dodged questions about the executive's status at an investor conference on Wednesday, insisting that he could not speak for Maffei and that he would have to comment for himself.
Maffei joined Oracle last June as president and CFO and was touted at the time as an "exceptional executive". He replaced Harry You who himself had been with the company for only nine months.
